No it's not urgent at all. Since there is no question here, you are just going to have to do some good old fashioned troubleshooting.

"when i opened it": which program do you use for that purpose? SQL Server Management Studio?
Where does that program run? On the same computer with the SQL Server proper, or on a different computer in the same local network or on a computer somewhere else remote?

First and foremost make sure that the SQL Server services are running. Other reasons could be, incorrect connection string or some Firewall blockage.

Here, have a look at this blog post to troubleshoot the issue : MSDN Blogs: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified[^]

If needed, look at these one:
Exception - error 26 - Error Locating Server Instance Specified[^]
provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance...[^]
"Specified SQL server not found" o..[^]
